Download or read book Sounding Rocket Delta Velocity System written by Edward F. McKenna and published by . This book was released on 1976 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sounding rocket tumble system to enhance deceleration and redirect the flight path angle of a vehicle can be an effective means of accomplishing large spacial separation between a separated payload and the spent final stage rocket motor. The design and implementation of two such systems, for 9-in. - and 17-in. -diam payloads, is presented. Flight test results show that separation distances between payload and vehicle in the order of 10 percent of vehicle apogee can be achieved. (Author).

Download or read book The D and E Regions written by William Swider and published by . This book was released on 1974 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of the E-region is fairly well understood and even many of the dynamical complications of this region have been successfully modeled on individual bases. Some of the major remaining problems of this region are discussed, in particular the nitric oxide concentration, a gas affecting the ratio of the two major E-region ions, O2(+) and NO(+). The D-region is much simpler than the E-region from a dynamical point of view but extremely much more complex from a chemical standpoint. Recent results from a study of the D-region under bombardment by solar protons is emphasized.

Download or read book Equatorial Scintillations written by Jules Aarons and published by . This book was released on 1976 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of satellite communications systems at frequencies varying from approx. 140 to 1600 MHz, as well as navigation and ranging systems in the 1200 to 1600-MHz portions of the spectrum, the effect of equatorial irregularities on fading signals has become of importance. Recent observations of the signal statistics of scintillations at frequencies ranging from 136 MHz to 6 GHz reveal a power-law falloff of irregularity sizes. Power spectra are now available for a variety of conditions and for frequencies from vhf to microwaves. during periods of intense equatorial activity at frequencies to 360 MHz, Rayleigh scattering is frequently experienced.
